. IMPRovED DEvIcE 'To OPERAI-E THE TrLTI'NG-,rLooRs yor MALT-xmNs'.

The Schedule referred to in these Letters Patent and making of the same.

To all whom it may. concern Be it known that I, JonN C. RHoDEsof thecit-y of' Chicago, in the county of Cook, and State of Illinois, haveinvented certain new and useful Improvel ments in""Device to Operate theTilting Floors of Malt-Kilns, 850., and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had tothe accompanying drawings, making vpart of thisspecification, and to the letters of reference marked thereon, likeletters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use myinvention, Iwill proceed to describe it.

My invention consists in an improved device adapted for the operation ofthe doors ot' malt-kilns, such .as

the iioors of the kiln invented by Joseph Gesmen, for which. LettersPatent were issued, on September '17, 1st?. y

The device inay also be used for all kinds of ioors, consisting oi'several strips, working on pivots, for the purpose of tilting saidstrips and unloading the oor loaded with grain, or other substances, atonce.

A is the wall of the building. y

B .O l) E F G are the floors, each consisting of a series oi' strips, ac, of perforated sheet-metal, or otherwise arranged.

b b are rods, on which said strips pivot.

The rods are journalled in walls or partitions of the building, andtheir ends protruding beyond said walls or partitions, are shaped intoor provided with cranks, c c, which 'cranks are connect-ed by plates orbars H H. Ordinarily, these bars, and through them the i'oors, areoperated by hand, by means of long levers, the

'short arms'of which areconnected with said bars H H, and the long armsextend down to the ground, there being as many levers as there arefloors; the disadvantage of this arrangement being'that sometimesmistakes occur in the handling of the levers,

and the grain from the wrong iioor is precipitated down, which makes a'great annoyance in a malt-kiln.

My improvement consists in aA device by which the.

oors are'tilted one after the other, without f til, and

which may be operated by hand, or by any motivepower.

It consists in the following:

Bars H H are provided with anges h h. 'An endless 5 chain, O, providedwith one or more lugs orcatches, K, is passed around pulleys, L L,operated by crank-handles or belts connected with steam or water-power.

M is a guide, for the purpose of keeping the chain at api-operdistance'from the wall, and facilitating the voperation of catches K onilanges h.

The arms supporting the pulleys and the guide are suitably'secured tothe building.

N N are springs secured to the wall, and bearing on the bars H H, forthe purpose of keeping them in place, and bringing them into originalposition, after they have been raised by the/catch of the chain Weightsmay answer for springs'.

The operationconsists-in this, that in ai'nalt-kiln,

when all the doors are loaded with grain, tlepart ot' the chain close tothewall, moving upward, thcatch K tilts the tloors one after the other,commencing with\ the lower floor.

By this operation, the grain of the lower floor is Witnesses:
